A bayesian approach for one-way ANOVA under unequal variances
In this report a Bayesian solution to the problem of testing the equality of the means of k independent normal populations with unknown and arbitrary variances is provided. An important issue in the solution of this problem ... -
A Bayesian approach to the multivariate Behrens-Fisher problem.
The multivariate Behrens-Fisher problem consists of testing the equality of the mean vectors of two independent multivariate normal populations with unknown and arbitrary covariance matrices. In this work we provide a ... -
A Bayesian Solution to the Behrens-Fisher problem
Girón González-Torre, F. Javier; Castillo-Vázquez, Carmen
(Springer, 2021-07)
A simple solution to the Behrens–Fisher problem based on Bayes factors is presented, and its relation with the Behrens–Fisher distribution is explored. The construction of the Bayes factor is based on a simple hierarchical ... -
Adaptive selective relaying in cooperative free-space optical systems over atmospheric turbulence and misalignment fading channels
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (Optica Publishing Group, 2014)
In this paper, a novel adaptive cooperative protocol with multiple relays using detect-and-forward (DF) over atmospheric turbulence channels with pointing errors is proposed. The adaptive DF cooperative protocol here ... -
Análisis de la capacidad ergódica en sistemas cooperativos de comunicaciones ópticas no guiadas
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (2015-09-14)
Ergodic capacity for the bit-detect-and-forward (BDF) cooperative protocol over gamma-gamma fading channels with pointing errors is here analyzed. Novel closed-form approximate ergodic capacity expression is here obtained ... -
Evaluating pointing errors on ergodic capacity of DF relay-assisted FSO communication systems
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (2015-09-15)
Ergodic capacity of decode-and-forward (DF) relay-assisted free-space optical (FSO) communication systems when line of sight is available is analyzed over gamma-gamma fading channels with pointing errors. Novel closed-form ... -
Impact of nonzero boresight pointing error on ergodic capacity of MIMO FSO communication systems
Boluda-Ruiz, Rubén; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen; García-Zambrana, Antonio (Optica Publishing Group, 2016)
A thorough investigation of the impact of nonzero boresight pointing errors on the ergodic capacity of multiple-input/multiple-output (MIMO) free-space optical (FSO) systems with equal gain combining (EGC) reception under ... -
Novel approximation of misalignment fading modeled by Beckmann distribution on free-space optical links
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (Optica Publishing Group, 2016)
A novel accurate and useful approximation of the well-known Beckmann distribution is presented here, which is used to model generalized pointing errors in the context of free- space optical (FSO) communication systems. We ... -
Outage capacity of rate-adaptive relaying for FSO links with nonzero boresight pointing errors
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen; Qaraqe, Khalid; qaraqe[et al.] (Institute of Electrical and Electronics Engineers, 2019-03-20)
An outage capacity analysis of a three-way free-space optical (FSO) setup based on the optical path selection, either source-destination (S-D) or source-relay-destination (S-R-D), with a greater value of channel gain along ... -
Outage Performance of Exponentiated Weibull FSO Links Under Generalized Pointing Errors.
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Carmen; Castillo-Vázquez, Beatriz; Hranilovic, Steve (IEEE, 2017)
Even in clear conditions, free-space optical (FSO) links are impaired by scintillation and dynamic misalignment which result in a slow fading channel. This paper presents the first characterization of outage performance ...
